    src/ssh/README.md TODO.md deucessh-conn.h deucessh.h ssh-conn.c ssh.c Log Message:
    I got 99 problems but a callback setter ain't one

    Enforce the "must set before dssh_session_start()" contract at
    runtime: all 8 session-level callback/config setters now return int
    and check sess->demux_running, returning DSSH_ERROR_TOOLATE after
    start instead of silently racing the demux thread. NULL cb remains
    allowed (means "no callback").

    Updated headers (deucessh.h, deucessh-conn.h), README.md, and
    TODO.md (item 99 done; items 95/96/101 moved to Closed).
